Professional Summary

Personal Web Page: http://homepages.uc.edu/~sousaae

Alex Sousa is an Associate Professor in the Physics Department with primary research interests on Experimental High-Energy Physics.  Prior to coming to the University of Cincinnati in 2012, he earned his Ph.D. from Tufts University, Medford, MA, under the supervision of Jacob Schneps in 2006. He went on to hold positions as post-doctoral Research Assistant at the University of Oxford, Oxford, UK, working with Alfons Weber, and Research Associate at Harvard University, Cambridge, MA, working with Gary Feldman.  His research work focuses in understanding and measuring the properties of neutrinos, being a member of three US-based long-baseline neutrino experiments, NOvA, DUNE, and MINOS+, that have made and will continue to make the most precise measurements of several neutrino oscillation parameters. Furthermore, they will address fundamental questions about neutrinos that have profound implications in our understanding of Universe evolution, such as whether neutrino interactions violate CP conservation, or how is the ordering of the three neutrino masses structured. Alex Sousa’s research has received major funding support through grants from DOE's HEP program and the SciDAC-4 Computational Science program. He is the recipient of a ORAU Ralph E. Powe Junior Faculty Enhancement Award (2014), and of a UC College of Arts & Sciences Risisng Star award (2017). He has been awarded three Fermilab Intensity Frontier Fellowships (2013-2014, 2018, 2019) supporting neutrino research at Fermilab and more recently the overall coordination of the installation, commissioning, and operations of the NOvA Test Beam detector and beamline.  In teaching, Alex Sousa has championed the use of active learning methods in the Department and served as departmental Teaching & Learning Liaison from 2016 through 2018. He is a 2018 Darwin T. Turner Breakfast of Champions Awardee, and an active member of the Department's Diversity and Inclusion Committee.

Research and Practice Interests

My research work focuses in understanding and measuring the properties of neutrinos. I am a member of three long-baseline neutrino experiments, NOvA, DUNE, and MINOS+, that have made and will continue to make the most precise measurements of several neutrino oscillation parameters. Furthermore, they will address fundamental questions about neutrinos that have profound implications in our understanding of Universe evolution, such as whether neutrino interactions violate CP conservation, or how is the ordering of the three neutrino masses structured. I am also interested in searches for  a new kind of neutrino that has no known interactions with other matter beyond gravity, called sterile neutrino. By comparing the energy spectrum from neutral and charged-current neutrino interactions in its two detectors, MINOS+ will be able to look for evidence of these sterile neutrinos, or place very stringent constraints on their existence.
